I really love the versatility of these bags. You can size them to fit your needs so they can hold greeting cards, tickets, gifts, even silverware for parties! You could even cut these in vellum to create your own glassine-like bags! All of these are compatible with both the 8x12 and 12x12 bags and follow the same tutorial. This bag comes sized at approximately 6-3/4" x 3-1/2" but can be sized to fit your needs. All of the elements can be used separately as well. You can find additional envelopes and a full tutorial HERE!
